The Schedule referred to in these Letters Patent and making part cf Athe sains.

To all 'whom it may concern.:

Be it known that- I, SAMUEL SHEPHERD, of Nashua, .in the county of Hillsborough, and Stateof Ncw'H'ampshire, have invented a new and useful Improvement in Machinery for Making Paper Collars, of which the following is a full, clear, and exact description, reference' being had tothe accompanying drawings, forming part of this specification/and in which- Figure 1 represents a.' plan of a machine constructed in accordance with my improvement.

Figure 2, a sectional elevation -of the same, taken as indicated by the line :c :n in ig.,1'.

Figure 3, a further sectional elevation, taken as denoted by the line y y. i

Figures 4 and 5, side and end views of certain devices connected with the feed of the strip or fabric through the machueyand Figures 6 and 7, similar'vicws of a modification of said device.

Figures 8 and 9 represent views of collars made and patched by my improved machine.-

My improvement has reference to machines for makving paper collars, in which the button-holes, or certain of them, are patched with any suitable material, sccured to the paper strip out of which the collars are formed, before or during its feed through the machine for cutting out the collar-blanks.

In myimprovemcnt for the production, iu au auto matic manner, of such collars, the paper out of which the collars are to 'be formed is fed through the machine in a continuous strip, of a suitable width corresponding to the width of the collar or collars to be iliade, while the material out of which the patches are stamped is also fed, in a continuous strip of suitable width, over the first-named strip, but at suitable angles to the rim of the latter. As the two strips are thus fed through the machinejihe patch-blanks are punched out of the one strip and stuck on to the other strip, the patching-strip 'having adhesive material suitably applied to its face for that purpose. During this sticking of the patches on vto the collar-strip, which occurs at suitable intervals in the feed of the strips, corresponding to the distance of the button-.holes apart, both the collar-strip and patch-stri p remain stationary. 'lo' enable the movement ot' the patch-strip to be susp nded at the time of patching, (while the patches are appliefh) its movementI is acceli-rrated during the int-ervals of time between'the .patchings. This is the geueral action o f the machine, which includes various novel features and combinations of details for making the same practicable' or efficient, as will be hereinafter. described.

.ttcr'erring to'the accompanying drawings- A is a bed, over or between which and a coverfB, through` a slot, a, the collar-paper, in the form of a' continuous strip, is passed, the same being drawn from or supplied by a roll or otherwise.

This strip, which is represented by the dotted line b, is fed in the direction indicated by thc arrow z, and is of a suitable Width to pass through the slot a, which may bc sutiiciently wide for two or more collars abreast to be formed out of the strip, and certain operatingparts be, duplicated or arranged accordingly; but it will here" sutce to describe the same as for making collars in single tile. Y

Saidpaper or collar-strip b is fed or drawn through the machine, over the bed A and extension A', to the latter, by the action of feed-rolls C and C', which may be geared together or made to operate in unison by frictionai contact or bite of wheels C C', but the lower one, C, of these rolls only is driven, as,for instance, by

belt and pulleys :l d', from a-Shaft, D, that derives' its motion, by gear-wheels e e', from amain shaft, E.'

The upper feed-roll C' is supported in a swinging frame, F, pivoted at `)Cso as to allow of said upper roll beingr brought down to bear orto release its pressure on the collar-strip b, according as it is required to feed the latter to the collar-forming cylinders G G', or to panse in supply of `the same thereto, while the patches or blanks are heilig stuck on to the collarstrip b. But while'thc collar-strip b is thus made to pause, for the purpose specified, by the release of pressure of the upper roll C', no actual pause takes place in the feed of it, so far as the run of the same through the collar-forming cylinders G G' is concerned, by reason of the rolls U U being geared to run faster than the cylinders G G', which have a continuous rotary motion, by means of gear-wheels e and g.

lhe cylinders continuously form the collars, and take up the slack in thest-rip as produced by this intermittent faster feed ofthe rolls C C'. The amount of slack and difference of speed estab- 4lished between the rolls C C and collar-forming cylinders G G', must be in accordance with the length of the collars or distance of the button-holes from one another.

The collar-strip bris held or clamped, while the patches or blanks are being stuck on it, bythe action of a clamp or holding-bar li attached to or projecting fromthe rear of the swinging frame F, whichsupports the roll C', so that when said roll G is pressing. down, for the purpose of producing feed of the collar-strip, the clamp isfrce or raised, and 'vice versc; that is, when the clamp H is down, or holding said strip stationary, the roll C is raised, and free trom bearing down on the collar-strip b and feeding the same forward.

The cylinders G G are suitablyfinished on their peripheries with diesfor embossing and cutting the collars in succession out of the collar-strip b,vand punching the button-holes therein as said cylinders take up said strip, in the slack, with the cloth patches or blanks arranged ou or 'cemented to it'at the proper places for the. button-holes. l ,l

The nteans for adjusting or timing the feedii1g-ac-- tion of the rolls C (fand duration of the clampingaction of the har H, on the strip, to suit various lengths of collars, also-the meansv for giving the said clamping-bar and feed rolls their necessary pressure on the strip, will be hereinafter described.

The patching strip h, of stout papel', cloth, or other suitable material,l out of whiclrthe patches are formed, and which may be prepared with adhesive material properly distributed o'n it, is supplied frotn a roll above, and fed intermittently across, or at right angles to the travel of the stripb, through and between clamping-rolls I I', the lower one, I, only being driven, and such lower clamping-roll also heilig made i to dampen the adhesive material onthe strip h, by its contact with water or other suitable tluids in a, trough, J, underneath it, any surplus supply of moisture bein g removed by a wipe-roll, K, that has spring pressure applied to its back. Said. patching-strip h, `in its run through the machine, passes over the bed-,cover or portion B, and to or through feed-rolls 'L L', that operate in connection with an endless delivery-apron, M, can'ied by the lower one, L, and a back-roll, N.

Such feeding-devices to the strip h should move in unison with the clamping-rolls I 1', for which purpose they may he connected by band and pulleys 'i t', and the necessaryintermittentmotion be connnunicated to them through a ratchet\vheel, 0, on the shaft of the feed-roll L, by means `of a pawl, 1, jointed to a lever, l, which'is connected with and operated by a vertically-reciprocatin punch-stock, Q.

This punch-stock t ways, and is operated by eccentric side straps R R, from or throlllgh eccentrics S S, on the mailt shaft E.

Said punch-stock has fitted to it, at its bottom, a punch-carrier;Q', having punches K K in it of the necessary size and shape required to form the buttonhole patches.

These punches may be set to occupy relative positions across or over the strip h, according to the necessary arrangement of the button-holes for any given formation of the collars out of the strip b, or distance of the adjacent hutton-holcs apart.

For this purpose, they maybe attached by setscrews, and triade removable, toft any of a series of holes in the carrier Q'orthe latter may have a socketfit or connection with the punch-stock Q, which will admitof said carrier 4being turned so as to swing or swivel the punches as required.

These punches, on the descent of the puuch-s`tock,.V

work through dies or holes in the bed-portion B, opposite corresponding openings in the portion A, titted with anvls Il, which parts should be suitably constructed to admit of their adjustahility, in conlbrmity with the adjustment -hercinbetbre referrcdto, of the punches k k, so that the latter, when adjusted, will be opposite or in line with the dies and anvils.

A piece or strip of rubber may he fastened on top of the anvils l l, to secure a soft and elastic action for the punches, as the latter, in descending, punch out the patches or blanks from the cementedand dampened portions of thestrip It, and carry them through the dies in the `bed-portion B, and stick them, by pressure, on the paper strips b, and afterward rise or retire for a repetition of such action.

To prevent the punches from becoming gummed or clogged by their repeated contact with the guunned or cemented portions of the strip It, and to keep the l dies through which they workalsotiee, I propose to have the punches work through stutting-boxes packed with paraline or other suitable cleaning-material, such works in suitable guides, or4

stuling-bo'xes to be arranged' on top of the bedportion B. a

The alternate action of the feed-rollerfO and clamp 'H to feed the patched collar-strip, and lto' secure the `necessary pause in the travel ofthe same, for the purpose ot'putting on the patches as described, as also the necessary pressures of these devices on the collarstrip, may be effected, iu part, hy aspx-ing presser-(bot,

T, connected with the punch-stock Q or lever P', and

arranged to bear down on the clamp l-I each time the punch-stock descends, and serving to keep said clamp hard down on the strip while the punches are putting on the patches. A

This depression of the clamp simultaneously raises the roll C and stops the feed, but on the punch-stock rising again, the weight of the roll C raises the clamp, and re-estahlishes the feed, by causing said rollto bite or bear on the strip. A spring pressure, however, may be substituted for the weight of the roll C', if desired. v

As a substitute for theV presser-foot T, I propose to employ adjustable means of a different character for timing, with the greatest ucety, the lift of the roll G', and for holding it raised till the patches have been secured on the strip b, also for establishing propel length of feed, and varying the same to suit ditferent lengths ot collar or distances ofthe button-holes from one another. Thus U, in iigs. 4 and 5, is a link orvertical slide, connected 'with the end or ends of the shaft of the roll O', andrca'rlying at its bottom an anti-friction roller, V, under or yagainst which rotating cams W W are brought to bear.V i

These cams lie face to face, and rotary motion is comnn-micated to them, at a proper velocity, by or through any suitable gear applied to their shaft m.

They are for the most part concentric with their shaft, but are each formed with a risc, or lift, n, which lift or lifts, when coming round under the roller V,

'raise the roll C' and depress the clamp Huwhich action isonly the reverse of operating on the clamp to lift the roll.

By making, however, the. one, \V, of these cams fast on its shaft m, or, preterably, adjustable by set-screws 'around the same, andthe other cam, \V, loose on said shaft, and adj ustahle, as by slots lr lfand set-.screws s s, on the face of the other cam, provision is made for not merely varying,r the time for lifting the roll .0', but

also for lengthening or shortening, as required, the

duration of itsA lift, according as the portions an are brought in lille or made to more or `less overlap each other, so as to produce a longer orshorter lift. In

this way may thel feed and retention from feed of the strip he regulated to the greatest nicety.

Where colla-rs of altcrnatelyfvaryiug length through.

out the strip are required, that is, tirst a long collar and then a short one, then suhstantiallythe same arrangement of means as shown in tigsr4 and 5 may be used, hut with the addition, as represented in tigs. and 7, ot'a second set ot' cams, n W3, with their lifts a n and roller V, which cams operate conjointly with or in succession to the cams W W1.

Oft-.ourse the driving-gear to the several motions may be varied to suit diticrent combinations and cir-.

cumstances, also various forms of collars may be triade by the machine, tor which purpose the collarforming cylinders G G' may be ofthe ordinary or any suitable construction. a

The patehingapparatus herein described may be used independently of the rolls G G', to simply patcl paper or other material which may be delivered in continuous lengths into any suitable receptacle, or he taken u p by a take-np roll, to be afterward cut .into collars or treated in any other way.

What 1 claim as my invention, and desire to secure by Letters Patent, is

1'. The arrangement of the rolls O C", for feeding the collar-strip, the rollsv L L', for feeding the patchstrip transversely to the collar-strip', :md the punches k k', for cutting out the patches, substantially as herein `specified.

2. .lhe combination, with the patching-devices, of feeding-devices opera-ting to feed the patched strips intermittently, substantially as and for the purpose herein described.

3. '.lhe combination, with the rising und falling fee@ or pressure-roll C', ofthe clamp H, operating intermittently on the collmlstrip, substantially as and for the purpose herein specified.

4. The combination, with the rising and fallingfeed -or pressure-roll G', ofthe cam or cams W W WzW, adjustable substantially as and -for the purpose herein set forth.

5. The combination of the feed-rolls L L' and clamping-rolls I I', for feeding the'pateh-strip, the punch'- stock Q, with its punches k k und their relative dies, vthe collar-strip feed-rolls O C', und theolamp H, the

whole operatingr together substantially as and for the` f purpose herein described.
